Generally, such calculating machines include drive means and actuating means whereby adding, subtracting, multiplying and dividing openations can be carried on with respect to an ac cumulator mounted in a. shiftable carriage. Figure 1 shows a calculating machine having a body it] on which a register carriage ii is mounted for endwise shifted movement. The machine is provided with conventional selecting and actuating mechanism controlled during calculated op- M is provided for controlling release of depressed numeral keys. Suitable mechanism including shift keys ill and ii is provided for shifting the carriage from orderto order. Key controls suitable means for causing resetting of the accumulator by power drive means. "lhe above mechanisms are generally conventional and their disclosure is not necessary to an understanding of the instant invention; and for that reason only the shiftable register carriage has been disclosed in this application.

Referring to Figure 2, a shiftable register carriage indicated generally at 2| includes the carriage frame 22 and the transverse bar 23 supported in spaced relation on the iraine 22 by similar end plates 24, only one of which is shown. The carriage provides a mounting for the numeral wheels or dials 26 of the accumulator and 277 of the revolutions counter;

Referring to Figure 2 and 4, each dial 26 is carried by a dial shaft 28 which is suitably journalled between the opposed halves of the carriage carries a ten tooth gear 29 by means of which values can be introduced into the accumulator as The alignmentof the desired figure on the dial with the sight opening 30 (Figure 1) in the cover 3| of the carriage is maintained by a suitable centralizing means ineluding a star-wheel gear 32 (Figure 4) mounted on numeral wheel shaft 28 and cooperating with a spring pressed ball 33. This mechanism is conventional.

To enable resetting of the dials 26 of the accumulator, each shaft 28 carries a. resetting gear 36 (Figures 4: and 7) with alternate gears (it offset axially along their shafts 28. Each gear 34 is mutilated as seen in Figure 2 for example, and

At its lower end the dial shaft 28,-

the mutilated portion is in the position shown in Figure 2 with the associated dial standing at zero. The eighth and ninth dials 28 have their gears a disposed below the gears 34 of the remaining dials for a purpose later described.

To perform the resetting operation. in connection with the gears 84 of the dials 28, a sectional resetting rack is provided as shown in Figures 4 and 9. having spaced alternately vertically offset gear segments ll formed on respective sets of parallel bars 31, a, and ll, of the respective sections. The bars of each rack section are secured in spaced relation by suitable spacers and studs I. Each gear segment It (Figure 8) has a cutaway portion II at one side thereof and a raised portion l! at the other side thereof.

As seen in Figure 9, the resetting rack is split with the left hand portion 31, associated with the seven lowest dials, the middle portion 38 associated with the eighth and ninth dials and the righthand section a is associated with the tenth order and all higher order dials 26. Rack sections 11 and I! are mounted for endwise sliding movement in the same track of the carriage frame and rack section I. is similarly mounted in lower parallel track.

Whena resetting rack section is moved endwise from the position shown in Figure 2 for example, i

it will serve to rotate any dials which are displaced from zero by engagement with their resetting gears ll until the mutilated portions of the resetting gears are aligned with the resetting rack when the drive will cease. In order to insure stopping of the numeral wheels or dials at aero without overthrow, a stop slide 48 (Figures 2 and 4) is mounted upon the upper surface of the carriage frame I! having a series of teeth 41 for engagement with respective st p ears ll carried by the dial shafts 28. The slide 46 i normally held inactive in the position shown in Figure 2 by -a spring a (Figure 5) and is temporarily moved to active position during a resetting operation as later described.

To operate the resetting rack 31 it is provided with a handle II, the construction of which may be similar to that of the handle Ii disclosed in l'igures 9 to 11 in the above-mentioned patent t0 Friden 2394.083. The handle II can be adlusted as explained in said patent to position an arm N for engagement with a pin it carried by operating slide I! which is slidably mounted for endwise movement on the carriage frame. The slide 1 is operable by power operated means of the character disclosed in said Patent Number 2,294.03, or is operated manually when the handlellismovedtotherightasviewedinl'igure 2 because 0! the engagement of handle I: with overlapping end portion lla of the slide ii.

To operate the stop slide 40 during resetting. the slide II has a pin a (Figure 2) which lies in front of the camsurface ll of the bellcrank Ii pivoted at I! on the carriage frame and-havin a pin and slot connection at 0 with the slide I.

As previously explained, the resetting rack 81 isassociatedonlywiththenrsttoseventh or lower order group of dials, so that operation of handle I! always operates to reset the first seven dials of the accumulator. The rack is assoelated with the tenth and all higher order dials can be selectively coupled for simultaneous resetting operation with rack 81 of the lower seven dials. and rack II for the eighth and ninth dials can be coupled selectively for operation either withrack 81 or rack a. The coupling of the'ten 4 and higher order group to the lower order group will be described first.

As seen in Figures 5 to 7, the resetting rack 1! associated with the higher order group of dials, is provided with a laterally extending arm 66 which extends through an aperture in the carriage frame and i provided with an upstanding ear 61. A bracket fixed to frame 22 carries a post 88 having a transverse pin 6! therein and receiving a sleeve 1i provided with a disc 12 having transversely aligned seats for the pin ll. Sleeve H is spring urged downwardly by spring 13 (Figure '7) held in place by operating handle 14 and a suitable retaining screw.

The ear 61 of arm 68 (Figures 5 to 7) is adapted for engagement by hook 18 adiustably pivoted at 11 on an extension of slide 51 and urged by spring I8 against a stop pin 19. As seen in Figure 5, tooth ll of hook 18 is engaged with ear ll 30 that the resetting rack 39 will be moved upon operation of slide 51. As seen most clearly in Figure 6, disc 12 carries a cam extension I which is adapted to be swung from the full line position shown in Figure 6 to the dotted line position where it will engage the camming surface provided by the back face of tooth II to lift the hook ll and tooth 8i thereof above ear '1. In this lifted position of tooth ll, endwise movement of slide 51 is ineffective to move the resetting rack II with the rack 31. Thus, if the handle II is adjusted to position cam extension I? as shown in dotted lines in Figure 6, resetting of the higher order dials of the accumulator will not occur in normal operation of resetting slide 51.

As previously stated, means is provided where by an intermediate group of dials (the eighth and ninth) can be coupled selectively with either the lower order group or the higher order group. Referring to Figures 8 and 9, the middle rack section 38 of the central rack carries an upright bracket II on which a walking beam lever I1 is pivoted at ll. Lever I! is subjected to the friction pressure of a double-ended leaf spring". The two ends of lever I! are provided with respective upwardly projecting teeth II and 02 for engagement with respective apertured ears I! and N of racks 31 and 3! respectively, so that by adiustment of lever I], the center rack section 3| can be connected for simultaneous movement with either of the adiacent resetting rack sections 31 or 30.

To enable adjustment thereof, lever I! (Figures 4, 9 and 10) carries a pin 06 engaged by the notched lower end of a key stem ll of key .8. Key 8| is mounted for endwisesliding movement on bracket II by engagement with a suitable guideway therein and by stud ill engaging a lengthwise slot in the key stem. Key II has an ear ll! overlying a lever I, pivoted at I" on bracket II. The opposite end of lever III is disposed beneath ear ill of key I" similarly mounted on the bracket u. Each of keys I! and-Ill is provided with a pair of latching receases Ill for engagement by an associated spring-urged ball"! to maintain the key resiliently in either raised or depressed position.

From th'eabove description it is seen that by suitable adjustment of the keys II and ill the lever II can be adJusted to connect central rack a with either of racks I! or 8! so that the resetting means can be split selectively at either the seventh order dial or at the ninth order dial. Figure 9 shows the adjustment for splitting of the resetting means between the seventh and eighth dials, while Figure 10 shows the adjustment for splitting between the ninth anditcnth dials.

tion. For example, if handle 53 Q To guard against accidental loss of the selective splitting adjustment during the resetting oporation, the walking beam lever 87 lsprovided with a pin i ii (Figures 9 and 10) which is adapted to pass either above or below a locking tooth M2 mounted on the carriage frame 22. Also the key stein ill is provided with spaced vertical notches M3 which are adapted for engagement y locking tooth ll l carried by a bracket lid on the stop slide 45.

To disable the splitting mechanism without changing the adjustment of the control handle i l to cause such splitting, the operating slide or rack Ea oi the power resetting mechanism is provided with a small key l2l (Figures 2 and 3) adjacent the manual handle 53 for the resetting mecha-- nism. The key will is mounted for sliding movement endwise of the rack 51 by means of a suitable pin and slot connection therewith, and is connected by a link I22 (Figures 2, 3 and 5) with a bellcrank i123 pivoted at I25 on the slide 5i. Spring 6265 urges pawl I23, link i222 and key ill to the positions shown in Figures 2, 3 and 5. The pawl i23 (Figures 5 and 6) is provided with cit-set ear 823, whch upon operation of the key EEG, is moved into the path of ear I29 of the resetting rack 39 which also provides a fastening for return spring |3| thereof. I If key ill is operated with handle 53, pawl l23 is moved to engage ears H8 and 129 so that rack 39 will be moved with slide 51 irrespective of the setting of the control handle M. In this way all of the dials can be restored to zero, irrespective of setting of the machine for normal split resetting operations.

From the above description it will be seen that the resetting means can be adjusted to obtain several desired results in the way of split pera= is adjusted as shown in Figure 2 so that arm is active and handle 14% is adjusted to make t e cam finger 82 inactive, operation of slide 51 will serve to reset all of the dials irrespective of depressionof keys 38 or lfil. lBy appropriate adjustment of handles 53 and "i l, the operation of slide 51 can cause resetting of the lower order group of dials alone or of the higher order group alone while the numher 01 dials in both the higher and lower order groups can be controlled by appropriate adjustment of keys 98 and IN. With key 14 set to disable the resetting means for the higher order group of dials, their resetting can be effected by operation of the small key l2! with the handle 53.
